Thermoplastic/thermoset grafted composites

Disclosed are thermoset/thermoplastic composites that include a thermoset component directly or indirectly bonded to a thermoplastic component via a crosslinked binding layer between the two. The crosslinked binding layer is bonded to the thermoplastic component via epoxy linkages and is either directly or indirectly bonded to the thermoset component via epoxy linkages. The composite can be a laminate and can provide a route for addition of a thermoplastic implant to a thermoset structure.

Pultruded beam reinforced with natural fibers, pultrusion system and method therefor

A system for pultruding a beam, such as a pultruded beam of natural fibers, comprises a pulling mechanism continuously pulling on a preform of yarns including a thermoplastic matrix and fibers, the pulling mechanism being downstream of the system. A sequence is provided in the system and has a pre-heating module to pre-heat the preform. A first die has a tapering channel portion heated such that the preform reaches a desired low viscosity temperature for resin in the thermoplastic matrix to impregnate the fibers. A vacuum module has a vacuum cavity to remove air from the preform exiting the first die. A second die has a tapering channel portion heated such that the preform is at the desired low viscosity temperature for resin in the thermoplastic matrix to further impregnate the fibers. A cooling module to cool the beam before the beam reaches the pulling mechanism. A system for pultruding beams is also provided.
